To all whom it may concern: than by a cam in one direction and a spring Be it known that I, LOUIS GODDU, of Winin the other direction, as most commonly chester, county of Middlesex, State of Massapracticed. I have simplified and improved chusetts, have invented an Improvement in the cutting mechanism for the wire, and also 5 Nailing-Machines, of which the following dethe means for moving the nose from cutting scription, in connection with the accompanyposition into position to let the nail be acted ing drawings, is a specification, like letters on by the driver. on the drawings representing like parts.

To stop-rod G, connected to said arm and rising provide for the automatically-variable feed and falling in unison with the horn, the lever 5 5 or the uniform feed of the wire, the wire- 13*, having connected to it the rod B are all feeding mechanism has been provided with the same as indicated by like letters in United what I denominate as a measuring-gate, it States Patent No. 403,835, dated May 21, 1889, being adapted to be turned aside when the and in practice the rod B is connected to a feeding of the wire is to be uniform. The lever attached tov the horn-shaft, so that the I00 50 awl and driver used are shown as actuated horn is lowered after each fastening has been positivelyin both directions by cams, rather driven and while the awl to be described feeds the work, said horn-shaft in practice being normally pressed upwardly by a spring during the driving operating, all as provided for in said patent, and said parts, being well known, do not require to be herein further described.

The stop-rod G slides at its upper end in a guide a, and said rod has mounted loosely 011 it a measuring-gate a, which when in its operative position, as shown by full lines, Fig. 1, (it being used only when the machine is being used for driving fastenings for uniting the sole to the shoe,) acts as a stop for the measuring-leg a also found in said patent, said leg being connected with an arm of a pawl-carring sleeve a (see Figs. 1, 2, and 5,) said sleeve having another arm a provided with spring-controlled pawls a (see Fig. 6,) which act 011 the toothed periphery of a ratchet-wheel 0?, connected to or forming part of a wire-feeding wheel a, suitably scored or serrated at its periphery to engage and feed the wire 20, being used, said wire being pressed against said serrated surface by a pressurewheel c mounted in a yoke or frame a ad.- justably attached to the framework by a screw a", said pressure-wheel having an annular V- shaped groove, the periphery of said wheel at each side said groove being serrated to bear against oneside of a flattened wire, the wall of the groove being also serrated to afford projections to engage either a quadrangular, square, round, or oval, or other shaped wire, a portion of which may enter said groove. The groove also acts to aline the wire with the wire-passages below.

The measuring-gate rises and falls with the stop-rod connected, as stated, to the horn, and consequently said gate when in working position, as in. Figs. 1 and 3, acts to stop the descent of the leg at sooner or later, and consequently shorten the back stroke of the pawls a, to thus effect at their next forward stroke a greater or less movement of the feed-wheel, to thus feed a greater or less length of the wire into the nose or carrier 6 to be described this operation being automatic, to thus provide for the length of fastening desired.

A roller or other stud a on a third arm of the pawl-carrying sleeve c is acted upon by a cam-surface (0 (see Fig. 5) at one side of the cam a, said cam-surface having a dep ression or space a, into which the said roller or other stud a enters, as required,when the pawl-carrier is moving on its back stroke to assume a starting-point, the roll entering said space more or less, according to the thickness of the stock, to thus provide for the required length of feed stroke next to be made.

The wire-guide (shown best in Fig. 6 and located just below the feeding-wheel)is composed of two plates 1) Z), the plate I) being provided next the plate 5 with a guidinggroove for the wire to be driven, the said groove being shaped to correspond substantially with the cross section of the wire,

whether round, flat, or otherwise, and to readily change from round to fiat wire, or vice versa, the plate I) may be readily removed from the machine, first by taking off, however, the frame a carrying the wheel a". The lower end of the plate I) is provided with a steel wear-plate I).

The driver-bar b is mounted in suitable guideways behind the fixed face-plate b of the head of the machine, said driver-bar having attached to it bya suitable screw a driver Z), which at its lower end enters a driver-passage Zfl (see Fig. 10) in a guide b connected to or forming part of a plate I)", attached to the head of the machine by screws b the edge of the said plate constituting a side guide for one side of the said driver-bar.

The awl c is attached to. the lower end of an awl-bar 0, provided at one side (see dotted lines, Fig. 3) with teeth, which are engaged by. teeth of an arm 0 forming part of a twoarmed lever mounted upon a stud-screw t and having a second arm a, which is provided wit-h a roller or other stud, (see Fig. 3,) which enters a groove 0 in the outer face of the cam-hub 0 fast upon the outerend of the main shaft 0 The rear side of the cam-hub c is provided (see dotted lines, Fig. 3) with a cam-groove 0, which receives a roller or other stud a", (see dotted lines, Fig. 3,) extended from the front of the driver-bar, said cam reciprocatin g said driver-bar positively up and down.

The shank of the awl-bar isadapted to slide vertically in guideways in a rocking frame (1, having-a sleeve-like hub d, which embraces a hub surrounding the main shaft in front of the cam-hub a. The rocking frame has attached to it at its front side by suitable screws the movable side guide (I for the awl-bar in its vertical movement, and at its rear side saidrocking frame has attached to it a guideway having a movable side (Z of a guideway, (see Fig. 1,) in which guideway is placed a swivel-block d, (see Figs. 5 and 5%) which is entered by a pin 40, extended from a clove tailed slide (1 provided at one face with teeth, said slide being fitted into a dovetailed passage in a rocking arm (2, connected to a short rock-shaft cl, having an arm (1 pro vided with a roller-stub which enters a camgroove (1 (see Fig. 5) at the outer side of the cam-hub (L said rock-shaft, by engaging the sliding block, moving the rocking frame to effect the feeding of the material, while the awl is in it, over the horn.

The arm (1 referred to carries a short studgear al (see Fig. 5%) the teeth of which engage the teeth of slide (1 and moves it with relation to the said arm and rocking frame to alter at will the length of the feed.

The main shaft has a cam 8, provided at its periphery with a groove in which is entered a roller or other stud of a toothed lever c,

pivoted at its upper end on a stud on the,

framework, the lower end of said leverhaving, as shown in Fig. 2, rack-teeth to engage the teeth of a block 2 (see also Fig. 7,) having within it a series of threads or annular be described, and then the throat is moved with the fastening into the path of movement of the driver. The throat referred to has a longitudinal movement from the position under the guideway for the wire to the position occupied by the driver, such movement being effected by the lever e, referred to. The throat receives the wire from an inclined wire-passage, and the driver works in a ver tical line, so the throat has to be tipped slightly in passing from one into its other position, and to effect this tipping movement I have placed upon the milled body of the shaft 6 a sleeve e fluted internally to fit the flutes or splines of said shaft, and also preferably for a short distance externally, (see right of Figs. 7 and 8,) and upon this sleeve I have mounted a lever 6", having a roller or other stud to enter a cam-groove at the rear side of the cam-hub (1 It will be understood that the shaft (2 may slide backward and forward to a limited extent within the said sleeve 6 and the block 6 by reason of its peculiar connection with said shaft by grooves and rings, permits the shaft to be rocked and reciprocated at the same time without either movement affecting the other.

The movable cutting-blade f (see Fig. 6)

is held in adjusted position by means of a cap-plate 2 and a screw 8 upon an arm f of the sleeve 6 The stationary cutter f is represented as held between the head of the machine and a detachable cap 4, held in place by a suitable set-screw.

When the wire has been fed into the movable throat for the proper distance, the sleeve referred to will be rocked to cause the movable blade or cutter to pass the lower end of the guideway for the wire and cut the wire off, and at the same time the throat will be tipped into its substantially vertical position, so that when it is moved forward, as described, the hole in the throat will come properly under the driver to enable the latter to strike the nail or fastening therein and drive it out from the throat. During the forward movement of the throat containing the loose fastening, the lower end of the fastening may ride on the top of a foot h until the throat has been moved far enough to come opposite the the hole h therein, the hole in which the awl works when feeding the material, and through which the fastening passes into the work.

When it is desired to change from nailing the sole to slugging the heel or quilting the sole, the operator will turn aside the measuring-gate a, and if a radically-different wire as to size and shape is to be used, the wireguide 6 may be changed, the driver and throat e to one having an opening of the desired shape in cross-section.

I have pivoted at upon the head of the machine an arm m, provided with a gage an, having at its under side suitable teeth to be engaged by the teeth of a hand-shaft m the gage being adjustable on the arm in order to place the fastenings at the proper distance from the edge of the sole, the entire apparatus being turned down'out of the way when it is desired to sing a heel or quilt soles. The arm referred to has two flattened portions 6 '7, against which acts a spring-pressed pin 8, it holding said arm either in its working or in its inoperative position, as desired.

The head of the machine has a socket n at its top provided with suitable notches a, and

into this socket is fitted a pin 12- or post, having a series of projections if, either of which may engage the said notch, and the said post has, as herein represented, three studs, on which are mounted three wire-carrying spools n n 42, containing different kinds of wire, either round, square, or fiat, according to the work to be done. The rod 07. maybe rotated more or less, as desired, to bring one or the other of said projections into the notch, thus bringing one or the other of the said spools into working position, according to which wire it is desired to use. The upper end of the spool is represented as provided with guides n for the shanks of brakes 02 which, acting by gravity, bear upon the surface of the wire on the spool and prevent it from overrunning.

The clutch-pulley mechanism for rotating the main shaft at desired times and the devices for controlling the same, as well as the brake, are and may be common to other nailing-machines. a

The pressure-wheel a (see Fig. 2) has an annular V-shaped groove in its periphery, and at each side of said groove the periphery of said wheel is serrated or scored, as are also the walls of said groove. This pressure-wheel acts upon the wire being used, of whatever cross-section, and presses the same against the scored periphery of the feeding-wheel a Providing the pressure-wheel with a V- shaped groove enables it to receive a wire of most any cross-section, such, for instance, as square, round, oval, &c., and the V-shaped groove enables a portion of the wire to enter more or less and bind therein. The scored periphery of the pressure-wheel, on the contrary, may act on the flat side of a wire and press the opposite fiat side against the feedwheel a Having described my invention, what I its actuating-pawl, and measuring-leg, combined with the movable measuring-gate, to operate, substantially as described.

2. The hollow sleeve 8 the movable cutter member operatively connected therewith, a complemental cutter-blade, a wire-guide,wirefeeding mechanism, a driver-bar having a driver, and a shaft located within said sleeve and provided with a nail-receiving throat, combined with devices to rotate said sleeve and with it said shaft to not only actuate the cutter, but also to oscillate said throat, and devices to reciprocate said shaft in said sleeve to enable the throat attached thereto to be put into position with the fastening contained in it in the path of movement of said driver, substantially as described.

3. The movable frame, having guideways for the awl-bar, and a block-receivin g guideway, and a rock-shaft having an arm provided with a guideway, combined with a slide-block and pinion intermediate said block-receiving guideway and said arm, whereby by adjustment of said slide-block by said pinion the length of feed effected by the awl carried by the awl-bar may be quickly regulated, sub stantially as described.

4. In a nailing-machine for forming nails from a continuous length of wire, the following instrumentalities, viz: a wire-guideway composed of two pieces I), I), one of said pieces being grooved to receive the wire, the other piece presenting a plane or ungrooved face to the wire, feeding mechanism to feed the wire through said guideway, and cutting mechanism to sever the said wire into nail lengths, the provision of making the wirereceiving groove wholly in one-half the guideway enabling said half to be readily changed to adapt the machine to the use of wires of different cross-sections, substantially as described.
